How To Setup Intellisense in VSCode for React.js

I’ve been getting back into React.js development and was missing the rich developer experience visual studio gives you with things like intellisense.

I thought I had something working as Ctrl+Space opened intellisense with a sensible suggestion, but this turned out to be the IDE using what I’d typed earlier to make an educated guess. Clever, but I was hoping for more.

No Intellisense

Before – No Intellisense

Dead Ends

Unfortunately I couldn’t find a simple “how to” guide and the stuff I did get from various github issues and stackoverflow didn’t really help.

After several dead ends and lots of hair pulling I eventually got intellisense working using these steps.

How To Setup Intellisense in VSCode for React.js

Step 1 – Create a jsconfig.json file

With a project folder open, look in the bottom right and you should see a lightbulb:

VSCode Lightbulb

VSCode Lightbulb

Click the lightbulb, and you should get a popup at the top of the IDE asking if you want to create a jsconfig.json file

Create JSConfig.json

Create JSConfig.json

Click “Create jsconfig.json” and vscode should do the rest.

Step 2 – Install Typings

The Typescript Definition Manager typings should be installed globally with

> npm install typings --global

This will allow you to install typescript definition files which is what we’ll do next.

Step 3 – Install React Typescript Definitions

In the folder of the project enter the following commands:

> typings init
> typings install dt~react --global

You should end up with a new “typings” folder with the following contents:

│   index.d.ts

Step 4 – Install typescript

You can install typescript globally, but I prefer to put it in each project with the following command

Npm install typescript@next

Which vscode detects automatically, so there’s nothing else to it.

Step 5 – Confirm it Works

Now you should be able to see some intellisense for react.js.

While attempting to get this working I found some what appears to be old and obsolete advice.

  • I haven’t created a CODE_TSJS or VSCODE_TSJS environment variable
  • There are also a couple places mentioning ‘tsd’, but that has been superseded by typings.
  • I don’t have (Salsa) in the bottom right of the IDE. In a different setup I had the version number of typescript, but that doesn’t appear to be essential.

In all honestly, I don’t really know what I’m doing, but it appears to work. Hopefully it will work for you too, but please let me know if it doesn’t in a comment below or on twitter.

    Works, after install typescript and restart visual studio code. Thanks..

    This worked for me. Thank you!

    I spent a full day trying to get intellisense working with react, working with eslint, working with vscode beautify, working with blah blah blah! I never had any intention of learning about typescript or typings or tsd.whatever lol! I guess thats how it goes in this line of work.

    Have you made any ground on this front? Is this still your way of setting things up? I wonder if it is really necessary to install typescript? I’m still trying to wrap my head around eslint config. Any insight?

    Thanks for the very helpful post.

      I’m glad it helped.

      From what I’ve read, support is much easier in the newer versions of VSCode. I think it comes with a version of TypeScript installed and it gets picked up automatically.

      Sorry, I haven’t kept up with ESLint.

    glad I found this tutorial in 2018! 🙂

    Everything worked in the recent version of VSC (1.19.2). There are just two small things that I needed to change for me:

    1. When attempting to “> typings install dt~react –global” it threw an error saying “Attempted to compile “react” as a global module, but it looks like an external module. You’ll need to remove the global option to continue.”

    Thats why I just removed the –global tag and everything worked just fine.

    2. I didnt need to install Typescript in my current directory to get Intellisense working.

    Thank you & good day, Sir! 🙂
